To all wit-0111, itjmaz'y concern;

Be it known that'I, CARL MUEHLEISEN,-Of

Baltimore, State of Maryland, have. invented a new and usefulImprovement iii Linotypelarly to linotype-machines of the generalv4l-.36,531 and 436,532, although it isjal'so applicharacter representedin Letters Patent of the United Statesissued toOttmar Morgenthaleronflthe lfithof September, 1890, Nos.

cable in other machines of analogous construction. v I a V In a linotypeas ordinarily constructed the operator manipulating the keyboard causes.

the matrices and spaces to be delivered from the magazines and composedor assembled in lines in a receiver, commonly known as'an assembler.When the composition of a line is completed, this assembler is liftedand the matrix-line is transferred at once through intermediatemechanism to the face of the mold for use. It frequently happens,however, that the. composition of a line is completed before the castingmechanism is in po- "sition to receive it, and in such event there is aloss of time on the part of the operator, who is compelled to wait untilthe line in the assembler can be disposed of preparatory to bc-V ginningthe composition of the next line of matrices.

The object of the present invention is to' avoid this loss of time andso contruct the posed of at once, and the composing opera tioncontinued, although the parts may not be at the moment in-position topermit the transfer of the completed line to the mold.

.To this end myinvention consists in a provisional means wherebyacomposed' line may be instantly transferred and held in abeyance untilthecasting mechanism is ready to receive it. r

The details may be varied in form and arrangement in many 'ways whichwill suggest themselves to the skilled mechanic after a consideration ofthis specification and the accompanying drawings without changing themode of action or departing from the limits of my invention.

The device consists, essentially, of two blades which areintroduced atthe right hand of the matrix-line as soon as composition is completed,one blade then shifting to the left and carrying the completed line intothe devices for receiving and transferring it, while the other bladeremains to keep the new line in course of composition in compact order,

the two blades being finallywithdrawn preparatory to use in due timebehind the secondlineJ- i V I have limited the drawings to myimproveddevices and to such parts of the linotype-machineasare necessary to ahunderstanding of the improvements. In all other respects the machinemaybe of ordinary construction.

Figure l is a front elevation showing the 'eratingblade.

Referring to Figs. 1 and 2, A represents an assembling belt of alinotype -machine on which the matrices D are received, one at a time,from the magazine and from which they pass downward over the supportin-rails B to a position in front of the rotary star-wheel G, which servesto crowd them forward, one after another, into the assembler-block E, inwhich they are composed or assembled in line, side by side, in the usualmanner, together with suitable spaces, until the line contains all thecharacters and spaces required in one line of print, so that it is readyfor transference to themold or casting mechanism preparatory to thecomposition of the next line in like manner. The foregoingoperation isessentially the same as in the ordinary'machine. The construction shown,however,

difiers from that of the ordinary machine in that the grooved orchanneled assembler E in the present instance is stationary, beingattached to or made integral with the machine,

whereas in the ordinary machine this assembler ismovable vertically inorder that it may be lifted to present the composed line to the transferdevices above. To effect this transfer of the line, I now provide thereceivingelevator F, arranged adjacent to the assembler E and mounted toslide vertically. It is grooved or channeled in the top to register withthe assembler, so that the composed line of matrices when completed maybe shifted horizontally to the left out of the assembler E into theelevator F, which, rising in due time, presents the composed linebetween the fingers G and G of the horizontallyslidingtransfer-carriage. This carriage is practically identical with that usedin the or dinary linotype, except that its fingers stand farther to the'left in position to receive between them the matrix-line presented bythe elevator. This carriage may be constructed and operated in allrespects in the same manner as the ordinary carriage of the Mergenthalermachine to transfer theelevated line to the left into the usual firstelevator, by which it is presented to the mold, and thereafter to thedistributing devices. The constructiouand operation of these parts formno part of my invention.

During the composition of the matrix-line in the assembler E the advanceof the line is resisted and the matrices held in close order by theupright finger h, which is urged constantly to the right by spring 7L,asnsual, the line being composed and confined for the time being betweenthe star-wheel G and the fin ger h. This finger instead of being madesolid, as usual, is made of U form, as plainly shown in Fig. 2, so thatthe line-separating fingers may .pass thereth rough, as hereinafterexplained. After the composition of the line is completed in theassembler E it must be transferred bodily to the left into the elevatorF, so that the composition of the next line may proceed in the assemblerE. In order to effect this transfer of the completed line and for thetime being to hold the matrices of the next line in compact order, Iprovide the two vertical bladesl and K, which receive vertical andlateral motions through mechanism hereinafter described in detail. Inorder that the action of these blades may be clearly understood, I willfirst describe their several movements and thereafter describe themechanism for effecting these movements. During the composition of theline the two blades stand together, with their pointed ends below thestar-wheel and to the right of the line, as shown in Fig. 3. \Vhen theline is completed and ready for transfer, the blades rise at the rightof the line, as shown in Fig. 4, the line being at this time confinedbetween the blade I and the finger h of the assembler-slide. The twoblades being now free to advance to the left, the composition of thenext line may proceed, its foremost matrix being supported by andagainst the blade K. During this action both lines will advance to theleft and the two blades will be carried forward between them. At theproper time, as soon as the transfer of the first line to the elevatoris demanded, the blade I separates from its companion and moves to theleft, as .shown in Fig. 6, carrying the completed line before it and.against the yielding finger it into the elevator F, which then rises,carrying the line of matrices upward between the fingers G and G of theshifter-carriage, which, moving to the left, carry the line forwardthrough the intermediate channel toward the casting mechanism, as usual.When the line is thus lifted clear of the assembler-finger h, the latterun der the infinenceof spring h returns to the right until it bearsagainst tle left end of the new line in course of composition, as shownin Fig. 7. It will be remembered that the finger is made of new form, sothat in returning to its normal position it may pass freely over theupper ends of the blades I and K. After the line has been lifted theblades I and K arelowered, closed together, and re turned to the rightto their original position below the star-wheel in order that they maytransfer the second line in the same manner that the first wastransferred. It will be observed that the foregoing action of the bladesadmits of the composition being carried on uninterruptedly and thatthere is no necessity for the operator to await the disposal of thefirst line before beginning the second.

' I will now describe the mechanism by which the blades are actuated.

The right-hand blade K is made of the form shown in Figs. 12 and 13,with its foot adapted to slide in the horizontally-grooved barL, (shownin cross-section in Fig. 2,) which is mounted on the upper end of thesupporting rod Z, arranged to slide upward and downward in guides L onthe main frame. The left-hand blade I is made of the form shown in Figs.14, 15, and 16, with an'extended end piece, which is also arranged toslide on the supporting-bar L, but preferably in a groove distinct fromthat containing the other blade, as shown. It will be observed that thetwo blades are free to slide to the right and left on the arm L, andthat the latter, being free to rise and fall, serves to raise and lowerthe blades.

The vertical movement of the blades is effected as follows: The verticalguide-rod Z is connected by link Z to a lever 1 pivoted in the mainframe and urged upward by a spring F, the effect of which is to lift theblades to and maintain them in their highest position whenever the leveris released. The depression of the blades is effected by extending thelever Z beyond its fulcrum Z and providing its upper end (see Figs. 1and 10) with a roller Z acted upon by a cam Z on the horizontal shaft M,which carries a driving-gear in, engaged, as shown inFigs. 1 and 2, by apinion m the shaft of which is provided with a and the blade I to theright, holdingthe ceases ,v v a grooved pulley m which may be driven bya belt from a pulley applied to any one of the constantly-running shaftsof the linotype-maother parts are at "rest. wheel there is a circularseries of studs m,

this finger-key at the proper time releases the lever and sets the partsin action, as follows: I

The gear-wheel m, being constantly rotated by its driving-pinion, ismounted loosely on theshaft M, so that it'turns freely, while the On=theface of the one or another of which may be engaged by theclutch-finger-m pivoted to the hub m fixed'on the shaft and acted uponby a spring on", which tends to. throw the finger m into' engagementwith one of the studs, which, sweeping the finger beforeit, will effectthe rotation of the shaft and cams. .In order to disengage the parts atthe end of each revolution, the oblique tripping-lip m isfixedto thelower rear end of the lever Z so that when the cl utch-armmTapproaches'its original position its-lower end will ride against theoblique lip, as shown in Fig. 2, so as to be drawn back thereby out ofengagement with the stud,

the lever being at this time held down by the finger-key N. Now whenthis lever is released, as before mentioned, its forward end rises andits lower end falls out of engagement with the clutch-finger m as shownin Fig. 10, allowing the latter to again engage the driving-gear. Itwill of course be understood that when the forwardend of the lever isdepressed by the action of the cam it is an tomatically engaged and helddown by the finger-lever N, this locking of the lever keeping the bladesI and K down and also keeping the rear end of the lever in position tohold the clutch-finger out of action, as shown in Figs. 1 and 2. I

The lateral movement of the bladesvto effect the shifting and separationof the matrix lines is effected as follows: The left-hand blade I has anear amounted to slide on a vertical rod 2 arranged to move horizontallyon a guide-rod i fixed to the main frame. The slide '1? is connected bylink i to the upper end of a lever-i pivoted to the main frame at. i andhaving its lower end connected by link i to a second lever i which ispivoted to the main frame at Z and provided at its lower end with aroller 2', acted upon by a cam i fixed on the before-mentioned shaft M.A tension-spring 1' connects the,upper end of lever 11 with the mainframe, a

as shown in Fig. 1, and serves through the intermediate parts to urgethe vertical rod 1" blade normally in the position shown in Figs.

1 and 3. The blade I serves to carry the blade K before it to theyright, and thesecond matrix-line as it increases in length forces theblade Kbefore it m the left, there being at one stage of the operationsa considerable distance between the two blades, as shown in Figs. 6,7,and 8. The frictional engagement between the blade K and thesupporting-bar L is such that the blade ofiers a suitable resistance tothe advance of the second line during the absence of the main resistanth, which, it will be remembered, is moved temporarily to the left in.advance of the first matrix-line preparatory to the transfer of thelatter. After the first matrix-line has been lifted clear of theresistant h the latter returns to its position at the end of the secondline in course of composition, as shown in Fig.

7, and itis after this action that the blades are drawn down andrestoredto their position at the right of the line. The resistant h is carried,it will be remembered, by the assembler slide or'bar H, whiehis providedwith the usual stop-shoulder 77. (See Fig. 1.) This stop, used to limitthe advance of the assembler and thus determine the length of the linewhich can be composed, instead of being arranged to encounter the usualstop is now arranged to abut against one end 'of a leverO, which Iprovide for the purpose. This leveris pivoted to themain frame F at 0and connected at its opposite end by rod 0 to the fin ger-key lever N,so that when this lever is released to start the mechanism for shiftingthe blades it at the same time moves the stop-lever 0, so that theassembler-slide may continue its movement to the left as demanded bytheshiftiug of the line.

' I believe myself to be the first to provide mechanism for assemblingthe matrices in a continuing line and dividing thisline by twocodperatin g fingers entering at the rear of the line into groupssuitable for use in producing the successive linotypes withoutinterrupting the course of composition. 7

It will be evident to the skilled mechanic that the details ofconstruction maybe greatly modified without departing from the principleof operation or the limits of my invention.

Having thus described my invention, what I claim is 1. In alinotype-machine, a matrix composing or assembling mechanism, anelevator for the composed lines, and a transfer mechanism comprisingmeans to shift a composed line from the assembler to the elevator andmeans to sustain the following matrices in the assembler.

2. In a linotype-maehine, a mechanism to compose the matrices in acontinuing line, in combination with two blades adapted to enter at theend of the line and separate lengthwise thereof, whereby the matricesfor one linotype may be separated from those following.

3. In a linotype-machine, mechanism for composing the matrices incontinuing lines, in combination with two blades or separators shiftingthem into the elevator.

5. In a linotype-machine, the combination of the composing mechanism,including the resisting-finger, the elevator, the two blades or fingers,and mechanism to advance said blades into and Withdraw them from theline and to move them laterally, substantially as shown and described.

6. In a linotype-machine and in combination with assembling mechanism,the two blades, I and K, the bar on which they are sustained andarranged to move laterally, a cam and connections to raise and lowersaid bar, and a cam and connections to move blade I to the right andleft.

7. In a linotype-maehine, a com posing mechanism in combination with ayielding resist= ant for the front end ofthe line, a second resistant orblade to enter the line in rear of the first, one being formed andarranged to pass the other without collision in the absence ofintervening matrices.

In testimony whereof I hereunto set my hand, this 1st day of May, 1899,in the presence of two attesting witnesses.
